From another one of those "Bush doing great now" stories in the WaPo:
[...]But when matched against the president, Dean fares badly, both in a hypothetical trial heat and on who is trusted to handle both national security and domestic issues. Even many Democrats said they still know little about Dean or his views.
The poll findings show why many Democrats are nervous about Dean as a potential candidate against Bush.
Then, a little further down:
No other Democrat was tested against Bush in the Post-ABC poll.
Control group? What control group?
I'm starting to sound like a Dean fanatic here. Really, I'm not; I think he'd be about a hundred times as good a president as Bush, and I admire his campaign, but the guy has a tendency to shoot his mouth off unwisely that bothers me. On personality alone, I lean toward Clark. But I'm becoming really annoyed with the prevalence of the "Dean will get stomped but Democrat X would win" story; I believed it myself a year ago because it sounded plausible, but there is as yet no actual evidence for it.
The Saddam bounce hasn't changed the fact that when polls match specific Democratic candidates against Bush, they all do about the same, except that Clark often does better by a point or two, not nearly enough to close the current gap. Comparing Dean to an unnamed Democrat is misleading, because specific challengers always look bad in those comparisons.
Meanwhile, I agree with Ruy Texeira about the bounce itself. He adds the interesting information that even Bush's popular support on domestic economics spiked temporarily during the Iraq war. I think Texeira tends to cherry-pick the most optimistic information he can find about Democratic hopes, but he's right here. If Bush wins it probably won't be because of any specific big event; it will be because he managed to hold onto that solid floor he has so far at about 51 or 52 percent.
A while back the Onion ran a joke about a public opinion poll about opinions of public opinion. As usual, the story was only about a millimeter off reality. I think it's fascinating, though, to see the large difference that can exist between what people think and what people think that people think. The tendency seems to be to assume that big, dramatic events mostly drive public opinion; when actually it takes a cataclysm like the WTC/Pentagon attacks to have any great lasting effect, even that fades, and the long-term trends are mostly driven by economics and general cultural attitudes.
